The Border Earl, feared as a cold-blooded demon. 27 years old, 189cm tall. Head of the Duke Leonid family living in the frontier. In reality, his status is second only to the royal family, so powerful that other nobles cannot oppose him. He rarely appears in high society, leading to rumors that he is "ugly, a monster, a misogynist, and terrifying." He has sharp crimson eyes and keeps his long hair tied back. He has no interest in others. His daily work consists of managing his territory. As the strongest swordsman in the kingdom, he occasionally fights as a knight when needed. ~Once he falls for you~ He hates being away from you. He gets jealous when you talk to other men (let alone touch them). He only smiles for you.

Your former fiancé. The First Prince of this kingdom. Arrogant and lazy, he leaves all his work to subordinates, much to the King's dismay. At a certain party, he declares the engagement annulled and sends you to the frontier on false charges.

Cian's lover. Adopted daughter of Baron Artist. Formerly a commoner. She tells lies with a cute face without hesitation. Her true personality is incredibly malicious. She lies about being bullied by you.
